Configured Blanking Services

Configured blanks are geometric shapes typically taken out of a precision blank which is any square, rectangular, or trapezoidal piece that is specific to the customer’s dimensions. Precision blanking is the process of running a coil through a die to be punched out in the desired geometric shape. During this process, a blanking punch that is shaped to match the desired part, is placed above the metal coil. A press is then used to drive the punch down into the die opening, thereby punching the blank from the larger metal sheet.

Chesterfield provides configured blanking services to assist in tool designs and builds. We provide configured blanks after review of the part and complete analysis to assure the proper material is chosen for production. Chesterfield can also offer Gauge Enhancement and Thickness Reduction. After thorough analysis and by choosing the correct material and processing, we can guarantee material as low as +/-.001”.

Chesterfield Steel can also serve as your supply chain management partner, allowing you to leverage our buying power, processing capabilities, expertise, and experience. We can work with you to help you manage your inventory by providing help in ordering, stocking, and shipping your material, including any special processing needs.

Steel blanking is the process of running a coil through a die to be punched out in the desired geometric shape. During this process, a blanking punch that is shaped to match the desired part, is placed above the metal coil. A press is then used to drive the punch down into the die opening, thereby punching the blank from the larger metal sheet. Press blanking machinery can typically process material up to 72 inches wide and .250 inches thick from coils up to 50,000 lbs.

In punching, the smallest amount of material necessary is removed from the original workpiece to minimize waste. Blanking operations are most efficient when the maximum amount of material is removed from the workpiece. Blanking results in the creation of multiple metal parts from a single piece of sheet metal, whereas punching typically creates a single hole in sheet metal.

Compound Die Stamping is a particular type of blanking production in which the die separates or blanks the part from the original steel in one stroke. A cost-effective method for stamping higher volume parts, a Compound Die will perform multiple punches in one stroke rather than multiple strokes. Additionally, the compound die is commonly used to produce blanks to close dimensional and flatness tolerances.

Progressive stamping, contrary to compound stamping, involves the use of multiple work stations, each of which performs one or more different operations on the part before it is moved to the next station; Hence the name, progressive. Utilizing a progressive die allows you to perform multiple cutting and/or forming operations simultaneously, produce components at a fast pace, and maintain consistently close tolerances.
